CodeT5 and CodeT5+

Official research release for CodeT5 and CodeT5+ models for Code Understanding and Generation from Salesforce Research, which are introduced by the following papers:

Title: CodeT5+: Open Code Large Language Models for Code Understanding and Generation

Authors: Yue Wang*, Hung Le*, Akhilesh Deepak Gotmare, Nghi D.Q. Bui, Junnan Li, Steven C.H. Hoi (* indicates equal contribution)

Title: CodeT5: Identifier-aware Unified Pre-trained Encoder-Decoder Models for Code Understanding and Generation

Authors: Yue Wang, Weishi Wang , Shafiq Joty, Steven C.H. Hoi

In practice, CodeT5 and CodeT5+ models can be deployed as an AI-powered coding assistant to boost the productivity of software developers. At Salesforce, we build an AI coding assistant demo using CodeT5 as a VS Code plugin to provide three capabilities:

  • Text-to-code generation: generate code based on the natural language description.
  • Code autocompletion: complete the whole function of code given the target function name.
  • Code summarization: generate the summary of a function in natural language description.
